Comparing the refrigerator

130 more |
|
|
After |
3 u |
+ 195 |
4x2 =
8 u |
|
130 ÷ 2 = 65
3 x 65 = 195
5 x 65 = 325
Total amount that Gabriel and Eric had at first
= 5 u + 325 + 10 u
= 15 u + 325
15 u + 325 = 865
15 u = 865 - 325
15 u = 540
1 u = 540 ÷ 15 = 36
Amount that Gabriel had left
= 3 u + 195
= 3 x 36 + 195
= 108 + 195
= $303
Answer(s): $303
